-8|10n-5|=-120

- 8 ∣ 10 n - 5 ∣ = - 120

n = - 1 or n = 2

Solution steps

- 8 ∣ 10 n - 5 ∣ = - 120

Divide both sides by

- 8

∣ 10 n - 5 ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

10 n - 5 = - 15 or 10 n - 5 = 15

10 n - 5 = - 15 or 10 n - 5 = 15

n = - 1 or n = 2

∣ x + 3 ∣ = - 5

\frac{x + 1}{2} + x = 6

∣ c - 25 ∣ = 15

∣ - w ∣ = - 15

∣ x + 4 ∣ = - 3
